Guys pls help me my N900 device memory is corrupted after i connect it to PC. The N900 got a virus w/c make my folder become a shortcut only and after i unplug if the memory is corrupted. No matter how i restore the original setting of my N900 nothing happens. Pls i need an urgent reply on this matter what should I do?? Will my files can be retreived??

Try to install rootsh first. You need it to apply the following commands through X-Terminal application:There might be an error here if the partition is not mounted, but you might just carry on.If more errors occur, please, feel free to post here.

It said "input/output error" and before that "FAT32 root dir starts with a bad cluster"

and also there are differences between boot sector and its backup.
cluster 2 and 5 out of range.

Please try Copy and paste the complete output of the errors here.

Or if copy and paste is not possible redirect the output to a file and attach the file hereThis command does not give any output, but creates the file /home/user/fsck.txt, where the error messages are written to.

It displayed "FAT32 root dir starts with a bad cluster"..I follow your command at first theres no umount because invalid argument then try to mount and then displayed the errors cluster 2 and 5.

Then type the "fsck -r /dev/mmcblk0p1 > fsck.txt no need to type the first command right?? and then nothing happens the same FAT error. Sorry im noob in x-term programming..

Ms. Michaaa62 right correct me if im not mistaken?? Theres a 50/50 chance that i should format this or clear device option if didn't solve in x-term (hope not =( because i have so many important files)?? Because i can't access the memory device when i connect it to usb or nokia pc mode..This site is my only hope because N900 in the philippines are all phase-out and there are few people whom i can rely on..=(

Has been a long day for me , sorry.

Safety first: If you have a linux pc available you could make a clone copy of the device via dd command. This would clone the whole partition to have a backup in the case something goes wrong

You could try to write the backup of the first sector (bootblock) to the partitionIf no errors occur, reboot to check if your files are still intact.

You could install recovery-tools package and have testdisk try to read the partition, and hence recover the files to some external microSD. Here is a short walk-through for testdisk http://talk.maemo.org/showpost.php?p...8&postcount=16 , but this might be a time consuming procedure, if testdisk finds your files and folders.

Good luck!

It's more helpful if you paste the *exact* commands and *exact* output here instead of describing it with words - avoids misinterpretations.

This is the actual argument displayed after typing the commands:

"$sudo gain root
root shell enabled

/home/user # umount /dev/mmcblk0p1
umount: cannot umount /dev/mmcblk0p1: Invalid argument

/home/user # fsck -af /dev/mmcblk0p1

The internal device memory was really corrupted i can't be able to access either usb mode or pc suite mode the memory and i can't save a note or take a picture because the memory is not present and can't access.
